================
Comment at: cmake/modules/HandleLLVMOptions.cmake:751
+mark_as_advanced(LLVM_ENABLE_IR_PGO)
+append_if(LLVM_ENABLE_IR_PGO "-fprofile-generate -Xclang -fprofile-instrument-path='${LLVM_PROFILE_FILE_PATTERN}'"
+  CMAKE_CXX_FLAGS
----------------
-fprofile-generate=<> is supported as well, why not using that?
